The configuration class is usually used to set the core configuration variables of CakePHP, which are in the app/config/core. php file. The following describes the variables and their impact on CakePHP.

Variable name description

Debug	Set the output mode for CakePHP debugging 0 = no output results 1 = Display error messages and warnings 2 = Display error messages, warnings, and database query statements 3 = displays error messages, warnings, and database query statements to complete the controller dump?

Cache. check	If this parameter is set to true, view cache is enabled. Although the controller cache needs to be enabled separately, this variable can monitor these settings.
Session. save	What is the session storage mechanism of CakePHP? Php = use the default PHP session storage Cake = Save session data to the/app/tmp Directory Database = Save the session to the database table. However, you must use the/app/config/SQL/sessions. SQL database query file to set the table.
Session. table	Name of the table storing the session, excluding the prefix
